This study observed that the ethyl acetate extract of Equisetum debile showed high activity against 5α-reductase and lipid peroxidation with no cytotoxicity on dermal papilla cells.

In this study, the researchers developed a new method using H2O2/TiO2/UV for extracting human hair keratins rapidly, yielding higher protein and enabling the production of keratin films with better hemostatic performance and varied wound-healing properties compared to films from traditionally extracted keratin.

This study suggests that ethyl acetate extract of Equisetum debile may be effective for functional food and nutraceutical use due to its strong 5α-reductase, IL-6 inhibition, and lipid peroxidation activities without cytotoxic effects.

This study examined how different hair dye processes affect hair structure at a molecular level, finding that oxidative dyes increase keratin porosity more than non-oxidative dyes, and highlighted emerging technology aimed at reducing hair damage while preserving color quality.

In this study, researchers investigated how different hair dye processes affect hair structure, finding that oxidative dyes disrupt hair more than semi-permanent dyes, and emerging technologies could help maintain hair health while achieving desired color.

This study reviews how different hair dyeing methods affect hair structure, showing oxidative dyes cause more structural damage than semi-permanent dyes, while new technologies aim to minimize harm while preserving color.

This study investigated the electron transfer processes in an iron-mediated DAMO–anammox system, finding that Fe3+ accelerated c-type cytochrome-mediated electron transfer and suggested that riboflavin acts as an electron shuttle and DIET may occur among these microorganisms.

This study isolated highly pure oleanolic and maslinic acids from olive milling residues, exploring their chemical reactions, including the formation of finasteride precursors.

This study reports that hair damage from bleaching is associated with the oxidative cleavage of fatty acid thioester bonds, detectable by measuring the decrease in mass spectrometry peak at m / z 76.

This review highlights that the RNA modification N⁶-methyladenosine (m⁶A) plays a crucial role in regulating wound healing and tissue remodeling, with dysregulation contributing to complications in chronic wounds, such as diabetic ulcers and burn injuries, through mechanisms like impaired angiogenesis and increased oxidative stress.

This systematic review suggests that human placental extracts may offer therapeutic benefits for non-communicable diseases such as liver pathologies and metabolic disorders, but larger trials are needed to confirm efficacy and understand molecular pathways.

In this article, researchers explored how blue light exposure affects the scalp and hair follicles, highlighting oxidative stress and hair growth disruptions, while emphasizing the importance of protective strategies like antioxidants and limiting light exposure.

This review highlights the complex role of scientific knowledge and professional expertise in safely performing chemical hair procedures, emphasizing the importance of education to prevent potential adverse effects like hair damage and scalp irritation.

This study found that male rats on a riboflavin-deficient diet gained significantly less weight and developed symptoms such as alopecia and dermatitis compared to control rats receiving riboflavin.

This review discusses genetic and epigenetic mechanisms that may contribute to aging and presents models suggesting that chromosomal changes could play a key role in the aging process; it reports no new experimental findings.

This study found that chemical and photochemical oxidative processes modify the main classes of proteins in hair, confirmed through microspectrophotometric, fluorescence microscopy, and electrophoretic methods.

Auxin promotes root hair growth through oxidative processes involving reactive oxygen species.

This narrative literature review by LUSTRAO examines the complex biological mechanisms influencing hair growth and loss, highlighting that androgen signalling, while significant, works within a network involving regenerative, inflammatory, and vascular processes, without establishing it as the sole explanation for conditions like androgenetic alopecia.

This review discusses the role of oxidative stress in hair greying and suggests that understanding melanocyte susceptibility at different follicular locations may help develop therapies for preventing and reversing the process; it reports no new experimental results.

This study found that using a high-viscosity, high-amine-content silicone fluid as a pretreatment can protect hair from bleaching and dyeing damage without affecting these processes.

This study analyzed how oxidative hair dye leaches from pigmented and nonpigmented hair during wash cycles, finding that melanin influences the dye deposition and leaching processes.

This review highlights the role of chronic stress, oxidative stress, and immune processes in the development of Hashimoto’s thyroiditis and polycystic ovary syndrome, emphasizing the potential of antioxidants in their treatment based on the existing literature.

This study found that bleaching significantly damages hair structure and increases combing difficulty, while dyeing with emulsifiers can partially reduce damage and improve combability, yet both processes cause notable protein loss.

This study found that adding dithiodiglycolic acid to the hair straightening process decreased chemical damage and preserved the structural integrity of the hair matrix compared to using thioglycolic acid alone.

This review explores the complex biological process of hair graying, highlighting oxidative stress, genetic factors, and interventions like antioxidants and genetic therapy as key aspects affecting the preservation of hair pigmentation.

This study examined the factors contributing to gray hair, such as genetics and lifestyle, and found that while graying correlates with some health conditions, it is primarily a physiological process rather than a pathological one.

This research outlines a chemical synthesis process for Finasteride, detailing the conversion of pregnadienolone acetate through various chemical reactions and modifications.

This review discusses the role of mitochondrial dysfunction in the ageing process and reports that its significance compared to other factors in mammalian ageing remains uncertain.

This study presents male pattern androgenetic alopecia (mpAGA) as a natural physiological process involving reversible transformation of hair follicles, but notes unresolved links with androgen mechanisms and highlights potential research avenues beyond androgen receptor signaling for treatment exploration.

This study concluded that a synthesis process for finasteride from pregnenolone acetic ester is inexpensive, simple, and achieves a good yield of 36.5%.
